Description

Technical Field

[0001] This invention relates to the field of wastewater filtration technology, specifically a wastewater filtration device and treatment method for river management. Background Technology

[0002] With the continuous development of living standards and industrial production, more and more garbage and sewage are being discharged into rivers, causing pollution and turning rivers into sewage accumulation sites. In order to protect the environment, relevant departments need to purify the sewage in the rivers so that it can be reused. Filtration is an important process in sewage purification. Traditional filtration devices simply filter solid waste from sewage. When the solid waste is large and plentiful, it is easy to clog the filtration device, causing the sewage filtration process to stagnate and the filtration efficiency to be low. At the same time, existing filtration devices only focus on filtering floating matter in sewage, but neglect the dehydration treatment of floating matter, resulting in sewage residue problems during the processing of existing filtration devices.

[0003] The announcement number is CN110734176B, which discloses a purification device for treating river water pollution. This device introduces the river wastewater to be purified into a dewatering cylinder through an inlet pipe. After flowing through the dewatering cylinder, floating matter, solid waste, and other impurities in the river water are filtered out. The wastewater, now free of solid impurities, then enters the purification chamber. As the dewatering cylinder rotates, centrifugal force causes dewatering. After dewatering, a hydraulic rod is manually controlled to discharge the dewatered solid waste. While this purification device can separate wastewater from solid impurities, the centrifugal force generated during separation causes solid impurities to adhere tightly to the inner wall of the dewatering cylinder. Furthermore, the discharge of solid impurities requires manual operation, making continuous operation inconvenient. Although the dewatering cylinder is tilted, impurities are not automatically discharged after centrifugal dewatering, requiring manual assistance from workers, thus increasing their workload.

[0004] Based on this, a sewage filtration device and treatment method for river management are provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

[0019] 2. This invention, by setting a first liquid tank and a second liquid tank inside the purification chamber, and by setting a first control mechanism and a second control mechanism inside the second liquid tank and the first liquid tank respectively, facilitates the discharge of purified wastewater from the second liquid tank by moving a sealing baffle through the second control mechanism when the wastewater in the first liquid tank is about to reach a set capacity. The first floating plate and the second counterweight facilitate continuous control. The first control mechanism inside the second liquid tank allows the automatic entry of wastewater from the first liquid tank into the second liquid tank by moving a stopper block through a fixed rod after the wastewater in the second liquid tank has been discharged.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] Example 1

[0035] In one embodiment, such as Figures 1-12As shown, a sewage filtration device for river treatment includes an outer casing 13, a filter component, a collection component, and a chemical treatment component. A partition is fixedly installed inside the outer casing 13, dividing the interior of the outer casing 13 into a filtration chamber and a purification chamber. The filter component and the collection component are both located inside the filtration chamber, and the chemical treatment component is located inside the purification chamber. The filter component includes a filter belt 11, which is disposed inside the outer casing 13. An inlet is connected to the upper end of the outer casing 13 at a position corresponding to the filter belt 11. The filter belt 11 has a protective frame 15 attached to its outer side. The outer casing 13 has a drive assembly at its upper end that rotates the filter belt 11. The collection component includes collection boxes 20, with three collection boxes 20 arranged in a circular array at equal intervals. Each collection box 20 has several connecting pipes 21 fixed to its bottom end, all of which are fixed to a mounting shaft 22. Each collection box 20 has a sliding base plate 23 slidably mounted inside it. One collection box 20 is located below one end of the filter belt 11, with the sliding base plate 23 at its bottom end... The components are fixedly connected to the output ends of several first spring telescopic rods 24, which are slidably disposed inside several connecting pipes 21. Each first spring telescopic rod 24 has a symmetrically provided fixed post 29 at one end. The outer casing 13 is equipped with a switching mechanism for several collection boxes 20 to squeeze and dehydrate solid impurities and automatically discharge them. The drug processing component includes a water pump 41, a first liquid tank 42, a second liquid tank 48, and a drug tank 64. The second liquid tank 48 is equipped with a first control mechanism for controlling the entry of sewage, and the first liquid tank 42 is equipped with a second control mechanism for controlling the discharge of sewage from the second liquid tank 48. The switching mechanism facilitates the automatic switching of several collection boxes 20, which facilitates the continuous collection of solid impurities. At the same time, during the switching process, the impurities inside the collection boxes 20 can be squeezed and dehydrated, and the solid impurities inside the collection boxes 20 can be automatically discharged. The first control mechanism facilitates the automatic replenishment of the sewage level inside the second liquid tank 48, and the second control mechanism facilitates the automatic discharge of sewage from the second liquid tank 48.

[0036] The drive assembly includes a first motor 12, which is fixedly mounted on the upper end of the outer casing 13. A drive wheel is fixedly mounted at the output end of the first motor 12, and the drive wheel is connected to a driven wheel via a belt. The driven wheel is fixedly mounted on a rotating shaft at one end of a drive roller. The drive roller is fitted onto one end of a filter belt 11, and a transmission roller is fitted onto the other end of the filter belt 11. Both the drive roller and the transmission roller are rotatably mounted inside the outer casing 13. A scraper 16 is fixedly mounted at one end of the protective frame 15, and the scraper 16 is in close contact with the outer side of the filter belt 11. The filter belt 11 is symmetrically provided with liquid guide plates 14 on its inner side. Both liquid guide plates 14 are inclined and fixed inside the outer casing 13. When it is needed to filter river sewage, the sewage is added into the outer casing 13 through the liquid inlet pipe. Then the first motor 12 is started, which drives the filter belt 11 to rotate. After the sewage with solid impurities is filtered by the filter belt 11, the solid impurities are intercepted at the upper end of the filter belt 11. The filtered sewage flows into the bottom of the filter chamber after being guided by the two liquid guide plates 14.

[0037] The switching mechanism includes a worm gear 34, which is fixedly mounted on one end of the mounting shaft 22. Both ends of the mounting shaft 22 are rotatably mounted within rotating holes inside the outer housing 13. A worm 35 meshes with the worm gear 34. First rotating plates are rotatably mounted on both ends of the worm 35, and these first rotating plates are fixedly mounted on one side of the outer housing 13. One end of the worm 35 is fixedly connected to the output end of a second motor 36, which is also fixedly mounted on one side of the outer housing 13. A circular plate is slidably mounted inside one end of the connecting pipe 21. A first return spring 26 is provided between one side of the circular plate and one end of the first spring telescopic rod 24. A sliding push rod 25 is fixedly mounted on the other side of the circular plate. One end of each push rod 25 extends into the mounting groove inside the mounting shaft 22. A mounting rod is fixedly installed inside the mounting groove of the mounting shaft 22. The mounting rod is triangular in shape. A pressing button 27 is fixedly installed on each mounting rod at a position corresponding to one end of each of the sliding push rods 25. The pressing buttons 27 and the second motor 36 are electrically connected to the control box 28, which is fixedly mounted on one side of the outer casing 13. A connecting rod is fixedly installed between one end of each of the two fixed posts 29. A sealing plate 31 is fixedly installed between the two collection boxes 20. A guide plate 30 is fixedly installed inside the outer casing 13 at the rotation direction of the two outermost fixed posts 29 below the filter belt 11. A corresponding position of the guide plate 30 is fixed inside the outer casing 13. A baffle plate 32 is provided, with a first fixing plate 33 fixed at one end of the baffle plate 32. A first guide plate 17 is provided below one end of the filter belt 11. The first guide plate 17 is fixed inside the outer casing 13. In use, when the filter belt 11 rotates, solid impurities move with the filter belt 11. When the solid impurities move to one end of the filter belt 11, they fall into a collection box 20. As the amount of solid impurities in the collection box 20 increases, the weight of the upper end of the sliding base plate 23 increases, causing the sliding base plate 23 to slide inside the collection box 20. When the sliding base plate 23 moves, it pushes the sliding push rod 25 to slide through the first spring telescopic rod 24. When one end of the sliding push rod 25 presses the squeeze button 27, the control box 28 starts the second motor 36. This causes the output of the second motor 36 to drive the mounting shaft 22 to rotate 120 degrees, switching to the other collection box 20. During the switching process, the first fixing plate 33 scrapes away excess solid impurities inside the collection box 20, while the sealing plate 31 seals the space between the first fixing plate 33 and the first guide plate 17. When the other collection box 20 moves below the filter belt 11, excess solid impurities fall into the collection box 20. Simultaneously, when the collection box 20 containing solid impurities rotates, the baffle plate 32 seals the opening of the collection box 20. At the same time, the two fixing posts 29 are in close contact with the guide plate 30, allowing the guide plate 30 to guide the fixing posts 29. The fixing posts 29 drive the first spring telescopic rod 24 to slide inside the connecting pipe 21.The first spring telescopic rod 24 pushes the sliding base plate 23 to move, causing the sliding base plate 23 to squeeze solid impurities inside the collection box 20, allowing wastewater to be discharged into the bottom of the filter chamber. As the first spring telescopic rod 24 slides continuously inside the connecting pipe 21, its output end retracts.

[0038] A discharge port is provided on one side of the outer casing 13, corresponding to the position of the collection box 20. A second guide plate 37 is fixedly provided at the bottom of the discharge port. One end of the second guide plate 37 is tightly attached to the collection box 20 and the sealing plate 31. A collection trolley 38 is provided on one side of the outer casing 13 and at one end of the second guide plate 37. In use, when the opening end of the collection box 20 containing solid impurities is disengaged from the baffle plate 32, the sliding bottom plate 23 is pushed to slide inside the collection box 20 under the action of the first spring telescopic rod 24. The sliding bottom plate 23 pushes out the solid impurities inside the collection box 20, so that the solid impurities are guided by the second guide plate 37 and fall into the collection trolley 38 for automatic collection. At the same time, the sliding bottom plate 23 can scrape off the solid impurities attached to the inside of the collection box 20 when it slides.

[0039] The water pump 41 is fixedly mounted on the upper end of the outer casing 13. The output end of the water pump 41 extends into the interior of the filter chamber. A mounting bracket 39 is fixedly mounted at the bottom end of the filter chamber and the input end of the water pump 41. A filter plate 40 is mounted on one side of the mounting bracket 39. The filter plate 40 is inclined. When the water pump 41 draws sewage from the interior of the filter chamber, the filter plate 40 can filter out smaller impurities in the sewage.

[0040] The first control mechanism includes a drain tank 43 and a second float plate 58. The drain tank 43 is connected to the output end of a first tank 42. A first drain pipe 47 is symmetrically connected to the drain tank 43. A sliding hole is provided at the bottom of the drain tank 43. A fixed rod 45 is slidably installed in the sliding hole. A stopper 44 is fixedly installed at one end of the fixed rod 45. The stopper 44 is slidably installed inside the output end of the first tank 42. A second return spring 46 is provided between the bottom end of the stopper 44 and the bottom end inside the drain tank 43. A third fixed plate is fixedly installed at the other end of the fixed rod 45. The second float plate 58 is hollow inside. A first guide rod is slidably installed in the sliding hole in the middle of the second float plate 58. The first guide rod is fixedly installed in the second tank. The second liquid tank 48 is fixedly installed at the bottom of the inner part of the outer casing 13. A first counterweight is fixedly installed at the bottom of the second floating plate 58, and an adsorption plate is fixedly installed at the bottom of the first counterweight. A permanent magnet 59 is fixedly installed at the bottom of the second liquid tank 48 corresponding to the position of the adsorption plate. Second fixing plates 57 are fixedly installed at the upper end of the second floating plate 58 and at both ends of the third fixing plate. A limiting block 60 is fixedly installed on the fixing rod 45. A limiting frame 61 is provided inside the second liquid tank 48 at a position corresponding to the moving position of the limiting block 60. The limiting frame 61 is slidably installed inside the fixing tube, which is fixedly installed on one side inside the second liquid tank 48. A third return spring 62 is provided between one end of the limiting frame 61 and one end inside the fixing tube. The limiting frame 61 is symmetrically provided with support plates at one end, and each support plate is fixed with a reset guide block 63 at one end. The reset guide block 63 is located above the second fixed plate 57. In use, when the sewage in the second liquid tank 48 is discharged, the second floating plate 58 moves with the drop in water level under the action of the first counterweight. When the second floating plate 58 moves the second fixed plate 57 and is in close contact with the third fixed plate at one end of the fixed rod 45, the second floating plate 58 continues to move, pulling the fixed rod 45 to move, causing the fixed rod 45 to move the plug 44. When the adsorption plate approaches the permanent magnet 59, the permanent magnet 59 pulls the second floating plate 58 down quickly, and at the same time, the fixed rod 45 pulls the plug 44 away from the output end of the first liquid tank 42. This causes wastewater from the first liquid tank 42 to flow into the drain tank 43. The wastewater from the drain tank 43 then flows into the second liquid tank 48 through two first drain pipes 47. Simultaneously, one end of the limiting block 60 is tightly attached to the bottom end of the limiting frame 61, thus fixing the fixing rod 45. When the water level in the second liquid tank 48 increases, the second floating plate 58, being hollow, can float on the liquid surface. Under the action of buoyancy, the adsorption plate detaches from the permanent magnet 59. When the permanent magnet 59 drives the second fixing plate 57 to contact the reset guide block 63, the reset guide block 63 pushes the limiting frame 61 to move. When one end of the second fixing plate 57 contacts the plane of the reset guide block 63, the limiting block 60 and the limiting frame 61 completely separate. Under the action of the second reset spring 46...This seals the outlet of the first liquid tank 42 with the stopper 44, preventing the water level in the second liquid tank 48 from increasing. The second liquid tank 48 contains a dosing assembly for purifying wastewater.

[0041] The dosing assembly includes a liquid tank 64 and aeration branch pipes 67. The liquid tank 64 is fixedly mounted on one side of the outer casing 13. A dispensing pipe is connected to the liquid tank 64, and a dispensing head is connected to one end of the dispensing pipe. A valve 65 is provided at one end of the dispensing pipe, and a gear 66 is fixedly mounted on the valve stem of the valve 65. A rack is meshed on the gear 66, and the rack is fixedly mounted on one end of a support frame. The other end of the support frame is fixedly mounted on a fixing rod 45. Several aeration branch pipes 67 are located at the bottom of the second liquid tank 48. Several aerators 68 are connected to each aeration branch pipe 67, and one end of each aeration branch pipe 67 is connected to an aeration delivery pipe. The input end of the aeration delivery pipe is connected to... The output end of the aerator 69 is connected. The aerator 69 is fixedly installed on one side of the outer casing 13. In use, when the second fixing plate 57 pulls the fixing rod 45 to move, the fixing rod 45 drives the rack to move through the support frame, so that the rack meshes with the gear 66 and drives the valve stem of the valve 65 to rotate, so that the valve 65 is in the open state. When the sewage in the first liquid tank 42 enters the second liquid tank 48, the medicine in the medicine tank 64 can be added to the second liquid tank 48 at the same time. When the fixing rod 45 returns to the initial position, the valve 65 is in the closed state. Then the aerator 69 and the aerator 68 aerate the sewage in the second liquid tank 48, so that the medicine and sewage are fully mixed, so as to purify the sewage.

[0042] The second control mechanism includes a pusher frame 55, which is fixedly mounted on the upper end of a fourth fixed plate. The fourth fixed plate is fixedly mounted on the output end of a third spring telescopic rod 54, which is fixedly mounted in a mounting hole at the upper end of the outer casing 13. A fifth fixed plate is provided below the pusher frame 55 and is fixedly mounted on the upper end of a first float plate 56. The first float plate 56 is hollow inside, and a second counterweight is fixedly mounted on the bottom end of the first float plate 56. A sliding hole is provided in the middle of the first float plate 56, and a second guide rod is slidably mounted in the sliding hole. The second guide rod is fixedly mounted on the bottom end of the first liquid tank 42. The output end of the third spring telescopic rod 54... A rotating top frame 53 is provided on the upper part of the rotating top frame 53. A guide rod 52 is provided above the rotating top frame 53. One end of the guide rod 52 is inclined and is fixedly mounted on one end of the sliding plate. One side of the sliding plate is fixedly connected to the output ends of several second spring telescopic rods 51. The second spring telescopic rods 51 are all fixedly mounted inside one side of the outer casing 13. A sealing baffle 50 is fixedly mounted on the other end of the sliding plate. The sealing baffle 50 is slidably mounted close to the bottom end of the second liquid tank 48. A second drain pipe 49 is connected to the bottom end of the second liquid tank 48 at the position corresponding to the sealing baffle 50. The second drain pipe 49 extends to the outside of the outer casing 13. In use, when the water pump 41 continuously draws and filters... When indoor sewage enters the first liquid tank 42, the increase in water level inside the first liquid tank 42 causes the first floating plate 56 to float on the liquid surface. When the first floating plate 56 causes the fifth fixed plate to be in close contact with one end of the push frame 55, the fifth fixed plate pushes the output end of the third spring telescopic rod 54 to retract through the push frame 55. At the same time, the output end of the third spring telescopic rod 54 drives the rotating top frame 53 to move. When the rotating top frame 53 is in close contact with the inclined end of the guide rod 52, under the action of the fourth fixed plate, the rotating top frame 53 pushes the sliding plate to move. The sliding plate drives the sealing baffle 50 to move, so that the second liquid tank 48 is connected to the second drain pipe 49, allowing the purified sewage inside the second liquid tank 48 to be discharged. When the rotating top frame 56... When the guide rod 52 is disengaged and positioned above the rotating top frame 53, the sealing baffle 50 returns to its initial position under the action of several second spring telescopic rods 51. The sewage inside the second liquid tank 48 is discharged and the interior of the second liquid tank 48 is sealed. At the same time, the second fixing plate 57 pulls the plug block 44 to move, allowing the sewage inside the first liquid tank 42 to enter the interior of the second liquid tank 48. When the sewage level inside the first liquid tank 42 drops, the push frame 55 gradually returns to its initial position under the action of the second counterweight. Since the rotating top frame 53 is rotatably connected to the output end of the third spring telescopic rod 54, the rotating top frame 53 no longer pushes the guide rod 52 to move when the output end of the third spring telescopic rod 54 returns to its original position.

[0043] Example 2

[0044] The difference from Embodiment 1 is that: a backflushing pipe 18 is provided at the bottom of the filter belt 11. The backflushing pipe 18 is located above the first guide plate 17 and is fixed inside the outer casing 13. The bottom of the backflushing pipe 18 is provided with several exhaust holes. The output end of the backflushing pipe 18 is connected to the output end of the air pump 19. In use, after the filter belt 11 conveys solid impurities into the collection box 20, the scraper 16 can clean the solid impurities attached to the outside of the filter belt 11. Then, after the filter belt 11 continues to rotate to below the backflushing pipe 18, air is discharged from the exhaust holes of the backflushing pipe 18, which backflushes the filter holes on the filter belt 11, causing the solid impurities in the filter holes of the filter belt 11 to fall onto the first guide plate 17. Under the action of the gas, the solid impurities on the first guide plate 17 fall into the collection box 20.

[0045] The above embodiment discloses a sewage filtration device for river treatment. When river sewage needs to be filtered, sewage is added into the outer casing 13 through the inlet pipe. Then, the first motor 12 is started, driving the filter belt 11 to rotate. Sewage containing solid impurities is filtered through the filter belt 11, where the solid impurities are intercepted at the upper end. The filtered sewage is then guided by two guide plates 14 and flows into the bottom of the filter chamber. As the filter belt 11 rotates, it transports the solid impurities to a collection box 20 below one end of the filter belt 11. As the amount of solid impurities in the collection box 20 increases, the weight on the upper end of the sliding base plate 23 increases. When one end of the sliding push rod 25 presses the squeeze button 27, the control box 28 starts the second motor 36, causing the output end of the second motor 36 to drive the mounting shaft 22 to rotate 120 degrees, thus affecting the other... The collection box 20 is switched. During the switching process, the baffle plate 32 can close the opening end of the collection box 20, the guide plate 30 guides the fixed column 29, and the fixed column 29 drives the first spring telescopic rod 24 to slide inside the connecting pipe 21. The first spring telescopic rod 24 pushes the sliding base plate 23 to move, so that the sliding base plate 23 squeezes the solid impurities inside the collection box 20, so that the sewage is discharged into the bottom end of the filter chamber. When the opening end of the collection box 20 is separated from the baffle plate 32, under the action of the first spring telescopic rod 24, the sliding base plate 23 is pushed to slide inside the collection box 20. The sliding base plate 23 pushes out the solid impurities inside the collection box 20, so that the solid impurities are guided by the second guide plate 37 and fall into the collection trolley 38 for automatic collection. At the same time, the sliding base plate 23 can scrape off the solid impurities attached to the inside of the collection box 20 when it slides.

[0046] Subsequently, the water pump 41 continuously draws wastewater from the filter chamber into the first liquid tank 42. As the water level inside the first liquid tank 42 increases, the first floating plate 56 causes the fifth fixed plate to press tightly against one end of the pusher frame 55. The fifth fixed plate, through the pusher frame 55, pushes the output end of the third spring telescopic rod 54 to retract. At the same time, the output end of the third spring telescopic rod 54 drives the rotating top frame 53 to move. When the rotating top frame 53 presses tightly against the inclined end of the guide rod 52, under the action of the fourth fixed plate, the rotating top frame 53 pushes the sliding plate to move. The sliding plate then drives the sealing baffle 50 to move. The movement connects the second liquid tank 48 to the second drain pipe 49, allowing the purified wastewater inside the second liquid tank 48 to be discharged. When the rotating top frame 53 disengages from one end of the guide rod 52 and is positioned above the rotating top frame 53, the sealing baffle 50 returns to its initial position under the action of several second spring telescopic rods 51. The wastewater inside the second liquid tank 48 is discharged, and the interior of the second liquid tank 48 is sealed. When the adsorption plate approaches the permanent magnet 59, the permanent magnet 59 pulls the second floating plate 58 down rapidly, while simultaneously pulling the fixing rod 45. The moving plug 44 disengages from the output end of the first liquid tank 42, allowing the wastewater inside the first liquid tank 42 to flow into the drain tank 43. The wastewater from the drain tank 43 flows into the second liquid tank 48 through two first drain pipes 47. Simultaneously, one end of the limiting block 60 is tightly attached to the bottom end of the limiting frame 61, thus fixing the fixing rod 45. When the water level inside the second liquid tank 48 increases, the adsorption plate disengages from the permanent magnet 59. When the permanent magnet 59 drives the second fixing plate 57 to contact the reset guide block 63, the reset guide block 63 pushes the limiting frame 61 to move. When one end of the second fixing plate 57 contacts the reset guide block 63, the reset guide block 63 pushes the limiting frame 61 to move. When the block 63 contacts the plane, the limiting block 60 and the limiting frame 61 are completely separated. Under the action of the second return spring 46, the plug block 44 seals the output end of the first liquid tank 42, and the water level inside the second liquid tank 48 no longer increases. When the sewage water level inside the first liquid tank 42 drops, under the action of the second counterweight, the push frame 55 gradually returns to the initial position. Since the rotating top frame 53 is rotatably connected to the output end of the third spring telescopic rod 54, when the output end of the third spring telescopic rod 54 returns to its original position, the rotating top frame 53 no longer pushes the guide rod 52 to move.

[0047] Simultaneously, when the second fixing plate 57 pulls the fixing rod 45 to move, the fixing rod 45 drives the rack to move through the support frame, so that the rack meshes with the gear 66 and drives the valve stem of the valve 65 to rotate, so that the valve 65 is in the open state. This allows the sewage inside the first liquid tank 42 to enter the second liquid tank 48, and the agent inside the chemical tank 64 can be added to the second liquid tank 48 at the same time. When the fixing rod 45 returns to the initial position, the valve 65 is in the closed state. Then, the air supply machine 69 and the aerator 68 aerate the sewage inside the second liquid tank 48, so that the agent and sewage are fully mixed, so as to purify the sewage.

[0048] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
